DO5 - Rescue Management Scenarios

The following are example scenarios:

Scenario 1

One of a pair of divers has a coughing fit underwater, looses his mouthpiece and goes unconscious. His buddy brings the casualty to surface using a CBL where he is found to be not breathing. The divers surface 100 metres from the shore. The remainder of the diving party are on the shore.

Scenario 2

A mass of bubbles erupts at the surface. A lone diver then appears at the surface as though from a rapid ascent, flounders about and quickly goes unconscious.

Scenario 3

Two pairs of divers are diving from a cover boat. One pair of divers surface and are recovered. Divers should actually be recovered so that they and their equipment are recovered/stowed as is their normal practice.

The second pair of divers then surface with one diver being raised by a CBL The casualty is found to be unconscious and not breathing at the surface.

Scenario 4

Three pairs of divers are diving from a cover boat. One pair of divers surfaces and is recovered. Divers should actually be recovered so that they and their equipment are recovered/stowed as is their normal practice.

A second pair is alongside the boat being recovered. One diver of the second pair is recovered into the boat when the throttle is accidentally knocked putting the boat into gear (simulated) and running over the second diver before it can be returned to neutral. The second diver's leg has been badly lacerated by the prop.

A third pair of divers is still underwater
